A large portion of the Hive Guardians that you need to kill are evade bugged. To top it off, all of the related storyline quests in Stormsong Valley are bugged in some way/shape/form causing a massive backup of players trying to finish these quests. This means that non-evade bugged bees are insta killed by one of the 100 other players trying to finish this quest. Making a 2 minute quest take 30 minutes.
For other quests that you need to click an item, there are 20 players mounted around it trying to click it at the same time as you, causing casting errors or not being able to see or click the item at all.
All of these issues are on server pop low times, I can’t imagine how awful these bugs would make it during high pop times!
